Add in card GPU pass through causing built-in video artifacts
Hi all- Yesterday I put together a machine that successfully passes the GPU through to a Windows 7 x64 VM, however once the VM starts up, the onboard video card showing the console for dom0 starts showing scrambled video, predominantly a single random color wiping the screen. Everything in the VM seems fine, video is accelerated, etc. Rebooting or stopping the VM has no effect on the on-board video, I have to reset the box to fix it. Here are the relevant specs: Intel Xeon E3 1230 V2 (Ivy Bridge @ 3.3ghz) Tyan SS512GM4NR C204 chipset - with an ASPEED onboard video chipset ATI Radeon 7750 - passed through to Win 7 VM Ubuntu 12.04 x64, kernel recompiled to include xen pcidev backend statically xen-hypervisor-4.1-amd64 4.1.2-2ubuntu2.1 kernel line: module /vmlinuz-3.2.19 placeholder root=/dev/mapper/xen-root ro xen-pciback.hide=(01:00.0)(01:00.1)(00:1d.0) /etc/xen/win7.conf: kernel="/usr/lib/xen-4.1/boot/hvmloader" builder=''hvm'' memory = 4096 vcpus=4 name = "win7" vif = [''bridge=xenbr0''] disk = [''phy:/dev/xen/win7,hda,w'',''file:/home/user/en_windows_7_professional_x64_dvd_X15-65805.iso,hdc:cdrom,r''] acpi = 1 device_model = ''qemu-dm'' boot="d" gfx_passthru=1 pci=[''01:00.0'',''01:00.1'',''00:1d.0''] sdl=0 serial=''pty'' vnc=1 vnclisten="0.0.0.0" vncpasswd="" viridian=1 hpet=1 acpi=1 apic=1 pae=1 And VM is created simply using "sudo xm create /etc/xen/win7.conf" Any help or suggestions greatly appreciated! -David

Re: Add in card GPU pass through causing built-in video artifacts
Also incase it is relevant, I noticed during boot up the following line: * Starting load fallback graphics devices [fail] I am also attaching the log file from starting the VM.
